The average mid-contract broadband price rise in 2025 added about 36 pounds a year to a typical bill, and the best switching deal available to the same household saved about 96 pounds before the exit fee. After the exit fee, the saving was 21 pounds. That is the number that should have been in the headline, and it is the kind of number The Bill Check exists to find.
The Bill Check analyses household bills in the UK: broadband, mobile, energy and water, plus the social tariffs that around eight million eligible households have not claimed. It began as a broadband site and broadband remains its strongest ground, but the same method applies to every bill: state the single figure that matters, show the full working in a table, and be willing to conclude that the switch does not pay.
There is no cheerleading here for switching, for staying, or for any provider. The site takes no referral fees, so it has no reason to send readers anywhere. When a “deal” only works because of a cashback that half of claimants never receive, that is said plainly.
Regular features include a mid-contract price rise tracker, a social tariff checker, and comparisons that include the costs providers leave out of their own tables.
The Bill Check is edited by Liam Hesketh, who has spent years analysing telecoms and utility pricing. It is an independent UK publication and does not give personal financial advice.
